What is 48 XXXY syndrome?
48,XXXY syndrome is a chromosomal condition in boys and men that causes intellectual disability, developmental delays, physical differences, and an inability to father biological children (infertility). Its signs and symptoms vary among affected individuals.
Can a person have XXYY?

Can you have 49 chromosomes?
Boys and men with 49,XXXXY syndrome have the usual single Y chromosome, but they have four copies of the X chromosome, for a total of 49 chromosomes in each cell. Boys and men with 49,XXXXY syndrome have extra copies of multiple genes on the X chromosome.
What happens if you have 47 chromosomes?
A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Is XXYY genetic?

What is it like to have XYY syndrome?
XYY syndrome is a genetic condition that occurs when a male has an extra copy of the Y chromosome in each of their cells (XYY). Sometimes, this mutation is only present in some cells. Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome.
What is XXY syndrome?
